Google was in top form at its I/O developer conference this week in San Francisco. It unveiled new products, conducted technical presentations, and pulled off a stunning skydiving spectacle. The event generated many headlines and attracted interest from both technology enthusiasts and the broader public.

Day one: tablets and skydiving

The opening day was mostly consumer focused. Google launched its much-anticipated Nexus 7 tablet (http://arstechnica.com/gadgets/2012/06/google-officially-reveals-7-quad-core-nexus7-tablet-with-android-4-1/) and unveiled a new version of its Android operating system, complete with a voice control system intended to rival Appleā??s Siri. The seven-inch tablet is priced to sell and is designed as a content consumption device with deep ties to the Google Play ecosystem.

Android 4.1, codenamed Jelly Bean, appears to be an incremental update with a tight focus on much-needed performance improvements. Google has done some deep optimization to squeeze out better graphics performance and improve responsiveness (http://arstechnica.com/gadgets/2012/06/android-4-1-jelly-bean-faster-smoother-more-delightful/) across the platform.
